You can find out for sure by testing Calibre from before that change: `guix time-machine --commit=262a1734e250f756471a066348381017b3e281d6 -- shell calibre` ... because that commit 262a1734 immediately preceded the removal of Calibre's transitive dependency on QtWebKit. Well, I tested an old copy of Calibre myself, from around January 7, and it doesn't help with this bug. Did you check if this bug has been reported upstream? https://calibre-ebook.com/bugs From unknown Fri Jun 13 10:35:03 2025 X-Loop: help-debbugs@gnu.org Subject: bug#54033: Calibre's ebook-viewer only shows white-on-white or dark-on-dark.

That's a big merge commit, and Calibre is only broken in one of the parents. I started to do a bisect between the bad parent and the commit which bumped Calibre's version, but it contains merges and --first-parent seems to be less useful there than in the earlier bisect session. I see a recent update to Calibre 5.36.0, but I'm taking a pause because waiting for QtWebKit to build is annoying. That is the summary of what I know now; I'm also happy to copy the rest of the emails back into this thread, with Leo's permission. Jacob.

I gave the Launchpad a cursory check but wasn't able to find what I was looking for. In addition, I scrolled back through the Git history a ways and found a commit that seems to have working Calibre at the same version. $ guix time-machine --commit=9d25ee30b188f9202cc14f7cd25ba8a1c3ec1a72 -- package --show=calibre name: calibre version: 5.21.0 ,,, $ guix time-machine --commit=9d25ee30b188f9202cc14f7cd25ba8a1c3ec1a72 -- shell calibre -- ebook-viewer brings up a working version of the reader. Thank you for the information about the time-machine command. I started to do a Git bisect on my copy of the repository, but found that it was intractable to build the versions of Guix necessary. Part of that seems to be related to some merges: Some of the candidate commits had dates from 2020 on them and the candidate set was rather large. Is there a smarter way to hunt down the commit where Calibre broke?

To: Jacob MacDonald In general, when bisecting a range of commits that includes merge commits, you should use the --first-parent option, which basically does the right thing with the merge when choosing commits to test. Can you keep trying and let us know the results? If it becomes infeasible, let us know and we can arrange to run the bisection next week (on vacation).

As luck would have it, bisecting the smaller set gives me 6dffced09ecda024e0884e352778c221ad066fd6 as the first bad commit. And that's the big merge. I'm guessing that the next step is to bisect some subset of what used to be core-updates-frozen, but I have not gotten there yet. > In general, when bisecting a range of commits that includes merge commits, you should use the --first-parent option Thanks again for the bisect help. That made the search much narrower and the builds far easier. Jacob.

The issue exists there too, suggesting further that the problem is in the dependencies somewhere. I haven't come across a working revision with Calibre 5.14 in my bisecting expeditions yet, but I suspect some of those would be broken in the same way. Bisecting the branch which used to be core-updates-frozen with --first-parent has so far been fruitless. I seem to be jumping dates and Calibre versions again, and my Git-fu isn't strong enough to narrow the range of commits I'm bisecting. Many of the commits from core-updates-frozen also appear to be unbuildable; I'm not sure if that's expected, my guix-daemon being too new, or something else. I'm looking at merges *from* master into core-updates and core-updates-frozen pre-6dffce as potential problem sites. Based on the diff between the working and broken parents of 6dffce, my hunch is that the regression lies in a dependency (likely something on the Qt side) as opposed to the Calibre recipe itself.

However, I did find another merge which may be of interest: b029be2ee0f81cdcbc14240ff426408085ab0a40. One side of it, ffb381856d0c6cc1a557b789f6b377cfa17002a0, contains a working version of Calibre 5.21. I can't verify that the other side fails due to the mentioned glib-networking blocker. However, the common ancestor of the commits in question is 8b1bde7bb3936a64244824500ffe60f123704437, which has an older but still working version of Calibre: 5.14. I'm out of ideas for the moment: The differences in the Calibre recipe between branches are very small, but I don't know how to bisect here more effectively, get the core-updates-frozen commits to build, or dig into the Python build process.

Rather, selection still works but only displays selection markers at the upper left corner of the screen. According to a bug report about Calibre, similar things can happen if the fonts are not properly installed (https://www.mobileread.com/forums/showthread.php?t=315146). However, I checked a working version and broken version of my Guix profile against one another and the fonts appear to be installed correctly in both trees. While doing that, I also noticed that __pycache__ directories only exist in the broken tree. Is that a signal of something going wrong or just a change in Guix's Python?

That's because most commits on the branch are not expected to build. For most of the branch's lifetime, it's merely a place to dump patches that cause rebuilds of the entire distro (e.g. a glibc update). It's only in the final stages of the core-updates cycle that we integrate those core changes into a working codebase. I think we'll have to fix this bug the old-fashioned way: debugging, or reporting it upstream.

The results of my attempt at diffing are described above; I intend to try modifying the build steps, but if there's any advice for debugging Python builds I'll gladly accept it. The changes to the Python build system between the working commit and the broken merge seem moderate, but I've only skimmed them. I haven't dived into changes to dependencies yet. When I installed the working version as described above, my desktop shortcut stayed broken until I relogged or started it from a fresh terminal. This seems like an environment issue to me, but the desktop files didn't change in relevant ways. > reporting it upstream Given the similarity in the breakage over versions, it seems unlike an upstream bug to me. The only similar issue I can find is the font one, and the fonts are properly installed in the broken tree.
